Gross or Net Income on a Loan Application? (Mortgage, Auto, Personal)

The short answer: use gross income for most loan applications. Lenders use gross to calculate your debt-to-income ratio (DTI). Self-employed borrowers are the exception - lenders evaluate net income from Schedule C or K-1.

Quick Answer by Income Type

W-2 Employee: Use gross salary
Self-Employed: 2-yr avg net Schedule C (with add-backs)
Social Security: Benefit amount (often grossed up 125%)
Rental Income: 75% of gross rents (vacancy factor)

Mortgage: DTI and Gross Income

Fannie Mae, Freddie Mac, FHA, VA, and USDA all calculate DTI using gross monthly income. Your gross monthly income is your annual salary divided by 12 (or your hourly rate times weekly hours times 52, divided by 12).

Worked DTI Example: $90,000 Salary

Gross monthly income: $7,500

Max housing payment (28%): $2,100/month

Max total debt (43%): $3,225/month (includes car loans, student loans, credit card minimums)

Self-Employed Mortgage Underwriting

For self-employed borrowers, lenders use Schedule C net profit (or K-1 ordinary income for partnerships and S-Corps) averaged over 24 months. Depreciation and amortization are added back since they reduce taxable income without reducing cash. Business use of vehicle and home office deductions may also be added back depending on the program.

Important: Gross Revenue Does Not Count

A freelancer with $200k gross 1099 revenue and $120k Schedule C net income is qualified on $120k (net), not $200k (gross). The lender sees what the IRS sees. Showing bank statements with $200k in deposits will not override Schedule C net income for Fannie/Freddie conforming loans.

Other Loan Types

Auto Loans
DTI is assessed on gross income, typically targeting under 40% total DTI. Down payment and credit score matter more for auto loan approval than for mortgages. Self-employed auto applicants may be asked for bank statements or two years of returns in addition to a credit check. Credit unions often apply more flexible income standards.
Personal Loans
Personal lenders (banks, credit unions, online lenders like SoFi and LightStream) typically use gross income for DTI. The ratio threshold varies by lender - many target below 35-45% total DTI. Cash-flow underwriting models (used by Upstart, some fintechs) may look at net income or bank deposits rather than gross, making them more accessible for borrowers with high pre-tax deductions.
Credit Card Applications
Credit card issuers ask for 'annual income' on applications. The FRB allows cardholders to include household income for applicants who have reasonable expectation of access to those funds (married, domestic partners). Most applicants report gross annual income. The income figure affects credit limit decisions, not approval per se (which is mostly credit-score driven).
Student Loans (Federal IBR/PAYE/SAVE)
Federal income-driven repayment plans (IBR, PAYE, SAVE) calculate monthly payments based on Adjusted Gross Income (AGI), not gross income. This is a significant distinction - AGI is lower than gross because above-the-line adjustments are subtracted. For private student loan underwriting, lenders use gross income for DTI similar to other private loan products.
Business Loans (SBA, Line of Credit)
Business lending uses Debt Service Coverage Ratio (DSCR) rather than personal DTI. DSCR = Net Operating Income / Total Debt Service. SBA uses business net income (not revenue) plus owner's salary to assess repayment ability. Many lenders require a DSCR of 1.25x or higher - meaning the business generates 25% more income than its debt payments. For sole props, personal and business income are combined.

Loan Application FAQs

Is DTI calculated on gross or net income?
Debt-to-income ratio (DTI) is calculated on gross monthly income for conventional, FHA, VA, and USDA loan programs. Fannie Mae and Freddie Mac both use gross income for qualifying purposes. This means your pre-tax salary figure is used, not your take-home pay. For a $90,000 annual salary, gross monthly income is $7,500 - the DTI calculation uses $7,500, not the $5,500 or so that hits your bank account.
How is self-employed income calculated for a mortgage?
Self-employed borrowers are typically evaluated on a 24-month average of net income from Schedule C (sole prop/LLC) or K-1 (S-Corp, partnership). Fannie Mae and Freddie Mac guidelines allow add-backs for depreciation, amortization, home-office deduction, and business use of vehicle that reduce taxable income but not actual cash flow. A 12-month average may be acceptable with strong compensating factors. Lenders vary significantly in how they apply add-back rules.
What counts as income for a loan application?
Lenders accept: W-2 wages, self-employment income (Schedule C/K-1 net with add-backs), rental income (typically 75% of gross rents to account for vacancies), Social Security benefits (often grossed up to 125%), retirement distributions, alimony and child support (if documented and recurring), investment income (dividends, interest documented over 2 years). Note: rental income on a property you are purchasing does not count until you have two years of landlord history.
Does a car loan use gross or net income?
Auto lenders primarily focus on credit score and debt-to-income ratio. DTI for auto loans is typically assessed on gross income, similar to mortgage DTI. The target is usually below 40% total DTI (all monthly debt payments / gross monthly income). However, auto lenders are less standardised than mortgage lenders - some use gross, some use net, some use a cash-flow model. Credit unions often have more flexible standards.
